退火的條件如下: For maximum softness and optimum magnetic and electrical properties, Carpenter HyMu "80" alloy should be annealed in an oxygen-free, dry hydrogen atmosphere with a dew point below -40°F (-40°C) at 2050/2150°F (1121/1177°C) for 2 to 4 hours. Furnace cool to 1100°F (593°C). From 1100 to 700°F (593 to 371°C), cool at a rate between 350 to 600°F (194 to 334°C) per hour. [ Last edited by 張?zhí)?on 2008-12-12 at 19:28 ] |
